The births and mergers of neutron stars and black holes, the most exotic objects in the universe, can launch the fastest cosmic jets (gamma-ray bursts; GRBs) and shake the very fabric of space-time with gravitational waves. GW170817, the merger of...

Exoplanet systems are expected to evolve with time as they age. In most cases though, the dynamical evolution of exoplanet systems over billion-year timescales are hard to observe. I'll describe how Galactic kinematics can provide accurate and...

The iconic spiral arms that decorate the disks of massive galaxies (like our own Milky Way) have been studied observationally and theoretically since they were first recorded 180 years ago, nevertheless the exact details of their nature remains...

All large-scale structure cosmologists are faced with the question: how do we robustly extract cosmological information, such as on dark energy, gravity, and inflation, from observed tracers such as galaxies whose astrophysics is extremely complex...
